SkinCeuticals Blemish + Age Defense Serum

A key member of the Blemish + Age Line Up, Blemish + Age Defense is a targeted, oil-free approach to treating adult imperfections and signs of aging. This 1st-to-market acid blend combines 2% dioic acid with an optimal alpha- and beta-hydroxy acid formulation, designed to prevent the formation of blemishes, minimize hyperpigmentation, and reduce the appearance of fine lines and wrinkles.

Specifically created for the concerns of the blemish-prone adult, Blemish + Age Defense goes beyond efficiently treating imperfections to also address signs of aging. Salicylic acid and capryloyl salicylic acid combat blemishes; glycolic and citric acids treat fine lines, wrinkles, and roughness; and the addition of dioic acid fights imperfections, reduces excess sebum production, and prevents hyperpigmentation that can cause the skin to appear prematurely aged.

Clinical studies on the Blemish + Age Line Up showed significant improvements in inflammatory and non-inflammatory blemishes, fine lines, and uneven skin tone while displaying exceptional tolerance and lack of side effects. Blemish + Age Defense is a highly tolerable, efficient treatment for aging, blemish-prone skin.

Start low (application amount) and go slow (frequency of use).
On any sign of irritation reduce the frequency of use until skin acclimates.

Products that contain Alpha Hydroxy Acids (AHAs) may cause initial flaking, tingling and irritation to the skin. For some this may be part of the normal resurfacing process. This improves as the skin ‘gets used’ to the treatment. AHA products may be introduced with less frequent use and application can be increased as the skin acclimatises. At first start by gradually introducing one AHA product at a time into your skincare regime. Also some breakouts may occur initially, due to purging of the follicles. Discontinue use if you have severe redness, itching, burning, rash, swelling or blistering.

Do not use if pregnant - this product contains salicylic acid.
